2. Selecting the Faucet Location
The drinking water faucet should be positioned with function, convenience
and appearance in mind. An adequate flat area is required to allow faucet
base to rest securely. The faucet fits through a 1
1
⁄
4
-inch hole. Most sinks have
pre-drilled 1
1
⁄
2
-inch or 1
3
⁄
8
-inch diameter holes designed for spray hoses. The
drinking water faucet may be installed using one of these holes, despite their
larger size. If these pre-drilled holes cannot be used or are in an inconvenient
location, it will be necessary to drill a 1
1
⁄
4
-inch hole in the sink or through
countertop next to the sink for the faucet.
CAUTION:
This procedure may generate dusts which can cause severe
irritation if inhaled or come in contact with the eyes. The use of
safety glasses and safety mask for this procedure is recommended.
CAUTION:
Do not attempt to drill through an all-porcelain or porcelain-coated
sink. For applications on these types of sinks, we recommend using
the sprayer hole or mounting the faucet through the countertop.
CAUTION:
When drilling through a countertop, make sure the area below the
drilled area is free of wiring and piping. Make certain that you have
ample room to make the proper connections to the bottom of the
faucet.
CAUTION:
Do not drill through a countertop that is more than 1 inch thick.
CAUTION:
Do not attempt to drill through a tiled, marble, granite or similar
countertop. Consult a plumber or the countertop manufacturer for
advice or assistance.
The following instructions apply to stainless steel sinks ONLY.
(A) Line bottom of sink with newspaper to prevent shavings, parts or tools
from falling down the drain.
(B) Place masking tape over the area to be drilled to help prevent scratches if
drill bit slips.
(C) Mark point with center punch. Use a 1/4-inch drill bit to drill a pilot hole
through sink.
(D)
Use a 1
1
⁄
4
-inch hole saw to enlarge hole. Smooth rough edges with a file.
3. Mounting the Faucet
(A)
Loosen stem-nut on faucet, remove metal slotted disc (if attached).
(B)
Attach large diameter 3/8-inch drain tube to barb fitting at the faucet base.
This tube should be long enough to reach the drain clamp in Step 4.
(C)
Locate the small diameter 1/4 inch drain tube connected to the drain
port of the GRO element. Route the tubing to the faucet and cut off the
excessive length of tubing. Retain extra tubing for connecting storage tank
to RO system.
(D)
Attach 1/4 inch drain tubing from RO system to other barb fitting at faucet.
(E)
Slide chrome plate and black rubber washer onto faucet by threading both
drain tubes through the holes on the plate and washer.
(F)
Slide white extension onto long threaded section of faucet. Open end of
extension should come in contact with base of faucet.
(G)
Apply 3-5 wraps of plumber tape to faucet stem. Screw quick connector
onto end of threads.
(H)
Wet end of 3/8" tube. Push into bottom of connector. Tug gently to be sure
connection is complete.
NOTE:
To remove the tube, push on the fittings' collar and pull the tube out.
(I)
Holding the faucet, feed the three tubes through the hole in the sink.
Position the faucet handle at a desired location
(J)
Center the faucet and slip slotted disc between the white extension and the
bottom of the counter or sink. Tighten the stem nut with a wrench until it is
tight.
(K)
Firmly insert goose-neck spout into faucet base.
4. Installing the Drain Clamp
NOTE:
If you have a single-basin sink with a disposal unit, call Technical
Support for options.
NOTE:
Before installing the drain clamp, check the drainpipes under the sink
